Logan Gunthorpe e654dfd38c nvme: fix memory leak caused by incorrect subsystem free 
When freeing the subsystem after finding another match with
__nvme_find_get_subsystem(), use put_device() instead of
__nvme_release_subsystem() which calls kfree() directly.

Per the documentation, put_device() should always be used
after device_initialization() is called. Otherwise, leaks
like the one below which was detected by kmemleak may occur.

Once the call of __nvme_release_subsystem() is removed it no
longer makes sense to keep the helper, so fold it back
into nvme_release_subsystem().

unreferenced object 0xffff8883d12bfbc0 (size 16):
  comm "nvme", pid 2635, jiffies 4294933602 (age 739.952s)
